Performance

This example output the following performance stats with an AMD Ryzen 9 3900X. Showing the possibility of tokenizing ~100,000 credit cards per second.

tokenized and stored 100000 credit cards in 1.058474365s retrieved 100000 credit cards in 5.353857633s tokenized, stored, and retrieved 100000 credit cards in 6.412331998s
